Can smart selection of ingredients, packaging, package

instructions and consumers’ choice of microwave ovens

assure that consumers’ microwave validation results

match yours?

Mains voltage varies within bounds set forth

by the American National Standards Institute

(‘ANSI’) in concert with NEMA and EEI

The standards have worked for 125 years, and so does your Microwave.

Right—so what’s the issue?
